Bug summary

After making sexond axes on the righr with twinx y_label for this second axes is on the right, but clearing (doesn't matter is it cla() or clear()) second axes breaks set_ylabel putting it on the left. Ticks for second axes are still on the right, so I don't see why y_label wouldn't also go there (thats why I think its a bug)

Code for reproduction

import matplotlib
import matplotlib.pyplot as plt

figure = plt.figure()
ax = figure.add_subplot(111)
ax2 = ax.twinx()
ax2.cla()#or clear() ; doesn't work both ways
ax.set_ylabel('ax_label')
ax2.set_ylabel('ax2_label')#expected to be on the right
plt.show()

Actual outcome

Expected outcome

after clearing ax2 is still on the right, I expected its label also to be on the right

Additional information

I saw that similar solved problems occurred with twinx()(it was something to do with mirroring), but I couldn't find solution for this specific situation
